Io sì

IO Sì jewelry is an expression of the most contemporary luxury, combining Italian-made artisanal excellence with the beauty of diamonds and the value of sustainability.

All collections pair refined design with SUN LAB GROWN diamonds, which are sustainable because they’re lab-grown, beautiful, and radiant for both their light and ethical character—destined to illuminate those who wear them.
IO Sì SUN LAB GROWN diamonds are the diamonds of the future, as no raw materials are extracted; instead, humans harness science and technology to create what is rare in nature, thus preserving the beauty of our planet.

An IO Sì SUN LAB GROWN diamond is chemically, physically, and optically identical to a natural diamond. Their light, carat weight, and perfection are classified by the 4Cs (Carat, Color, Clarity, Cut).
IO Sì SUN LAB GROWN diamonds are created using technology that, through extreme pressure and heat, reproduces the environmental conditions under which natural diamonds form deep within the Earth over millions of years. The history of natural diamond mining is far from brilliant in terms of social responsibility and environmental impact.

IO Sì chooses only SUN LAB GROWN diamonds because they cause no harm to the environment. Unlike mined diamonds, they do not lead to social conflicts, violate human rights, or exploit child labor. For these reasons, they are both ecologically compatible and socially responsible.

Currently, there are two main technologies for creating high-quality diamonds in specialized laboratories:
• The High-Pressure High-Temperature (HPHT) method, which places a diamond seed with pure graphite carbon in a lab chamber at extremely high temperatures.
• The Chemical Vapor Deposition (CVD) method, which places a diamond seed in a sealed chamber filled with carbon-rich gases that are heated until the gases start bonding to the seed, gradually forming the diamond atom by atom.

All IO Sì SUN LAB GROWN diamonds come with a certificate of authenticity and are analyzed and certified by the same grading laboratories used for natural diamonds, meeting the same international standards.

IO Sì is the brand representing a new symbol of love and sustainable jewelry founded on contemporary values of luxury: authenticity, universality, and accessibility. This is why the brand supports initiatives for a better future alongside numerous organizations and associations.
